Changing Units of Measure
5. If sander does not sand the top of your
board, raise the table 0.01" and re-run the
board.
1. Press “SET” button (A, Figure 16) once, and
two changes will occur. First the present
value will change to "uuuu". Second the
“SET” button indicator light will illuminate.
6. Repeat Step 5 until the wide belt sander
lightly sands the entire top surface of your
calibrating board.
2. Now press “UNIT” button (B, Figure 16)
once. The present value should now read
inches, and the "Inches" indicator light
should be illuminated.
7. Measure the thickness of the board using a
pair of calipers.
8. Enter the measured thickness value from
Step 7 on the keypad. The value keyed in
will be displayed as the SV (Set Value).
Note:
To change back to millimeters from
inches follow the same procedure – press
the “SET” button then “UNIT” button.
9. Press the SET button. The PV readout will
now display "uuuu". Also, the SET indicator
light will be illuminated.
Sanding to a Specific Thickness
1. Key in the desired thickness setting on the
keypad. The desired thickness setting will
be displayed as the set value.
10. Press the SET button again.
11. The PV and SV readouts should now both
display the measured thickness of your
calibrating board.
2. Press the “RUN” button (C, Figure 16). This
will cause the table to move up, or down
until the set value is achieved.
3. While the table is moving you will notice that
the run indicator light will be illuminated.
Note:
do not feed material through the
sander while the conveyor is raising or
lowering.
Calibrating the PV (Present Value)
The controller should be recalibrated in a variety
of circumstances: whenever the platen height is
adjusted, changing brands or grits of abrasive
belt, setting up the machine for the first time, or
the operator feels that the machine is not
sanding to exactly the proper thickness.
The following sections will describe the use of a
calibrating board. The calibrating board should
be made of a hardwood.
1. With the sanding belt and feed belt turned
“OFF”, place your calibrating board on the
feed belt and slide it into the machine.
2. Use the “UP” button (D, Figure 16) to raise
the table so that the pressure rollers are
about 1/32" above the calibrating board, see
Figure 17.
3. Remove calibrating board from sander and
turn the feed belt and abrasive belt “ON”.

4. Use the “UP” button to raise the table 0.02",
as indicated by PV (Present Value) and run
the calibrating board through the sander.
